Alright, so just updated my version (currently on github) such that each thread an independent evolving weave timing parameter.  To compare to mine with Sunny's most recent update, I used the testnet where my version found 30 confirmed blocks in 10 minutes while the original code found 16 confirmed blocks.  I feel that this is a legitimate comparison because there were no other nodes on the test net currently mining (I know this because my client found every continuous block in both cases).  This comparison was performed with a t61p IBM laptop with a T9300 Core 2 Duo processor.  The current difficulty on the testnet is 5.4426.  

Going to test this with the 8 threads on my Core i7 next.
